Qualcomm’s case against Arm puts its ecosystem neutrality on trial

The value of being neutral

For decades, Arm has licensed processor technology and its instruction-set architecture to Qualcomm, Apple, MediaTek, Microchip, Nvidia, NXP, Samsung and others. That let companies including Amazon, Apple and Google design their own processors. Arm’s role has often been compared to Switzerland: a neutral presence in the semiconductor market.

Its technology spans devices from watches and electric toothbrushes to smartphones, PCs, cars and data centers. That reach makes the ecosystem difficult to replace.

Qualcomm acquired Nuvia in 2021 to strengthen its development of Arm-compatible processors. On the first day of hearings, evidence presented to the court indicated that Arm is considering making finished chips and pursuing markets in cloud computing, edge systems and physical AI.

Qualcomm’s allegations

Qualcomm says Arm benefits from its position in the industry, including its knowledge of licensees’ businesses, as it enters markets where those companies compete. Meta, Microsoft, Google, NVIDIA and Samsung were among the companies mentioned.

The dispute also concerns the tools and terms Qualcomm needs to develop its processors:

RISC-V came up as one possible way to reduce the strategic risk of relying on the owner of a proprietary architecture.

The case Arm has yet to make

So far, the court has mainly heard Qualcomm’s arguments and testimony from its CEO, Cristiano Amon. Arm has yet to present its account.

I think the key issue is not simply whether Arm can compete with its licensees. It is whether companies can keep relying on a supplier that may enter their markets. That question matters beyond Qualcomm: the harder Arm pushes into adjacent businesses, the more its neutrality becomes something the ecosystem has to judge, rather than take for granted.
